The strongest research methods for psychological
studies are: qualitative findings versus quantitative; experimental rather than descriptive or correlational; controlled - experiment, meta - analysis, and observation designs over archival, case
study, computational modeling, content analysis, field experiment, interview, neuroimaging, quasi experiment, self - report inventory, random sample
survey, or
twin study; and prospective (where subjects are recruited prior to the proposed independent effects being administered) and longitudinal (where subjects are
studied at multiple time points) rather than retrospective or cross-section
study.
Cadillac overtook Lexus to top a
survey of customer satisfaction with dealership service departments, giving General Motors
twin victories in a benchmark
study released today by J.D. Power and Associates.
